REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2800
Break out the IA32/X64 GCC inline functions that can not be used
in a unit test host application into their own source file. This
does not make any changes to the BaseLib library instance. This
is in preparation for a new BaseLib instances that is safe to use
with host-based unit test applications.
